## Long description

Double terminal ferrule Trytyt DUID-2X4.0-12 is a twin crimp ferrule for terminating two conductors of 4.0 mm² each. Supplied in a pack of 100, the ferrule provides insulation support at the wire end and ensures consistent, secure connections in control panels, terminal blocks and other industrial wiring applications. The ferrule's metal sleeve and insulated collar reduce strand fraying and simplify insertion into screw or spring-type terminals when used with a suitable crimping tool.
Advantages
This twin ferrule design enables reliable termination of two 4.0 mm² conductors in a single terminal position, saving space and improving wiring neatness. The insulated collar protects against short circuits and improves handling during assembly. Using a crimp-style ferrule increases mechanical strength and contact stability compared with bare-stranded conductors, reducing the risk of loose connections and rework.
Suitable for
 Control panels and switchgear wiring
 Terminal block and distribution strip terminations
 Industrial machinery and automation cables
 Power and grounding connections where two conductors share a single terminal
Key specifications
 Number of conductors: twin (2 conductors)
 Conductor cross-section: 4.0 mm² per conductor
 Construction: metal crimp sleeve with insulated collar
 Packaging: pack quantity of 100 pieces
 Intended termination method: crimp (use with appropriate crimping tool)
How to use
Strip each conductor to the appropriate length for the ferrule collar, insert both conductor ends fully into the metal sleeve, and position the ferrule in a compatible crimping tool. Apply a single crimp to the ferrule according to the crimping tool manufacturer's instructions to obtain a secure mechanical and electrical connection. After crimping, insert the ferrule into the terminal and fasten the terminal screw or engage the spring clamp to complete the connection.
Usage recommendations
For reliable results, use a crimping tool calibrated for ferrules of this cross-section and inspect crimps visually and mechanically. Do not attempt to use the ferrule without proper crimping, and avoid combining conductors of different cross-sections. Store the ferrules in a dry environment to prevent corrosion of the metal sleeve.
